you'd still need a bypass circuit so the fridge can be used while using the boat.
and if you forgot and left the bypass switch on when you came and tied up to the dock, you'd still be in the same situation as you are now. something that would cut out with voltage would be auto all the time with no manual intervention needed.
In fact the Combiner100 has provision for automatically bypassing when the boat is in use, a simple jumper from the remote
control to +12 on the DC panel would allow fridge operation and disable it when the tied up at the dock except when shore power
Despite your vendetta to downgrade our Combiners for using 10 gauge connection cables
, we have been manufacturing them now for over 21 years, all with UNCONDITIONAL warranty and there has never been a warranty return due to the 10 gauge cables
being inadequate. If you did manage to overload it, all our Combiners have self resetting thermal shutdown that is monitoring cable temperature and will limit maximum temperature to about 85C.
Your confusion arises from ignorance on the published specifications regarding maximum current
for various gauge wires. Those specifications are based on percentage voltage loss over DISTANCE which is important for having sufficient voltage at the destination
. With a rating of 55 amps, a cable doesn't suddenly melt when you put 56 amps through it.
The resistance of the Combiner100 cables is 0.003 ohms so the voltage loss on a maximum load of 100 amps is 3/10 volt. But as the current
drops during charging
, the voltage drop across the Combiner100 also drops to zero so the batteries get a full charge.
